A magnetic field is used to suspend a wire of mass 0.05 kgkg and length 0.16 mm . The wire is carrying a current of 11 AA . What

pochemuha

Answer:

$B=0.27840\ T$

Explanation:

Given:

mass of the wire, $m=0.05\ kg$

length of the wire, $L=0.16\ m$

current in the wire, $I=11\ A$

Now form the Lorentz force we know that every current carrying wire experiences a magnetic force on it due to the magnetic field components perpendicular to it.

Mathematically given as:

$F=I.L\times B$

$m.g=I.L\times B$

here: we nee to balance the gravitational force on the mass.

$B=$ magnetic field

$0.05\times 9.8=11\times 0.16\times B$

$B=0.27840\ T$

This magnetic field must be perpendicular to the direction of current in the wire and the these two directional quantities must lie in a plane normal to the direction of gravity according to the Fleming's left hand rule.

Children in a tree house lift a small dog in a basket 4.90m up to their house. If it takes 201J of work to do this, what is the

scZoUnD [109]

Answer:

4.18 kg.

Explanation:

Work done: Work is said to be done when ever a force move a body through a given distance. The S.I unit of work done is Joules (J)

Mathematically, work done is expressed as

W' = F×d.................... Equation 1

Where W' = work done, F = force , d = distance.

making F the subject of the equation,

F = W'/d............................. Equation 2

Note: The force need to lift the small dog n a basket = combined weight of the dog ans the basket.

Therefore,

W = F

Where W = combined weight of the dog and the basket.

Also

W = Mg

M = W/g............................. Equation 3

Where M = combined mass of the dog and the basket, g = acceleration due to gravity.

Given: W' = 201 J, d = 4.90 m.

Substitute into equation 2

F = 201/4.9

F = 41.02 N.

Since F = W = 41.02 N and g = 9.81 m/s²

Substitute these values into equation 3

M = 41.02/9.81

M = 4.18 kg.

Thus the combined mass of the dog and the basket = 4.18 kg.

Answer:

The atoms of noble gases already have complete outer shells

Explanation:

so they have no tendency to lose, gain, or share electrons. This is why the noble gases are inert and do not take part in chemical reactions. ... atoms of group 0 elements have complete outer shells (so they are unreactive)
